摘要：
This paper is concerned with the Cauchy problem of the Klein-Gordon-Schro center dot dinger (KGS) equations with a defocusing nonlinearity in three spatial dimensions. The global wellposedness at H2regularity level and the growth bounds for the corresponding Sobolev norm of the solutions are obtained by applying Koch-Tzvetkov type Strichartz estimates and modified energy, which removes the restriction of the smallness for the initial data in the previous literature and extends the exponential growth bounds to polynomial case.
